/* We are interested in the following hid0 bits:
6 - ECLK - Enable external test clock (603 only)
11 - DPM - Turn on dynamic power management (603 only)
15 - NHR - Not hard reset
16 - ICE - Instruction cache enable
17 - DCE - Data cache enable
18 - ILOCK - Instruction cache lock
19 - DLOCK - Data cache lock
20 - ICFI - Instruction cache invalidate
21 - DCFI - Data cache invalidate
24 - NOSER - Serial execution disable (604 only - turbo mode)
24 - SGE - Store gathering enable (7410 only)
29 - BHT - Branch history table (604 only)
I made up the tags for the 604 specific bits, as they aren't
named in the 604 book. The 603 book calls the invalidate bits
ICFI and DCI, and I have no idea why it isn't DCFI. Maybe IBM named
one, and Motorola named the other. */
